UNITED STATES PATENT OFFICE.

lNlPROVED INVALIDS TABLE.

Specification forming part of Letters Patent No. 23,068, dated March 1, 1859.

T0 LZZ whom, it may concern:

Be it known that I, JONATHAN M. ALLEN,

of Vorcester, in the county of Worcester and State of Massachusetts, have invented an Improvement in Invalids Tables and the mod'e of supporting them in the desired position, the construction and operation of which I have described in the following specification and illustrated in its accompanying drawings with sufficient clearness to enable competent and skillful Workmen in the arts to Which it pertains or is most nearly allied to make anduse my invention.

My said invention consists in the construction and arrangement of parts hereinafter described, by which I furnish a table for invalids, capable of being firmly and securely supported in any part of a room Without occupying any very considerable amount of space with the base of the table.

In` the accompanying drawings, Figure lis an elevation showing the middle portion in section. Fig. 2 is a plan with some of the parts removed.

' A is a pedestal which forms the lower portion of a column for the support of the other parts. The upper4 part of this pedestal is tubular, as shown in Fig. I, to receive the upper shaft B, Which also forms aportion of the same column. The shaft B terminates in a round ball or globe, "and is surmounted by a cap C. The height of the Whole is made adjustable by so construct-ing the parts as to allow the shaft B to slide into or be drawn up out of the pedestal. For the purpose of securing and carrying out this adjustment I fit a sleeve b to the shaft B, which sleevemaybe fixed upon it at anypoint by means of the set-screw d. The lines D and E indicate, re-

spectively, the iioor and ceiling of a room in is then adjusted so that it bears upon the nut or handavheel F, Which is attached t-o the pedestal. The sleeve is then fastened upon the shaft B, and this shaft is then forced up by the hand-nut F, so as to bear firmly against the ceiling, by which the Whole column becomes firmly fixed in its position.

. The bed or leaf G of the table is attached to a bracket H, the inner end of which fits into apertures formed in projections of the hub or collar I, which fits loosely upon the pedestal A. This collar I is made adjustable to Vary the height of the table and yet allowed to revolve bymeans of the collar J, which is so attached to it as to move up and down With it, and yet in such a manner as to allow one to revolve upon the other. This collar J is secured in position upon the shaft by means of the setsereW e. A set-screw f furnishes the means of preventing the tablearm from turning upon the shaft to secure the table for the time being in a yfixed position. The column should be set near the bed of the invalid, and this done the leaf or bed of the table may loe very easily swung around in front of the sick person or turned entirely out of his or her way, as occasion may require. The patient may also manage it With ease by means of a string or some kindred or equally simple device, and yet it is obvious that considerable *pressure may be applied to the table Without danger of upsetting it. The invalid may even assist himself to rise by bearing upon it Without forcing it from its position.

I claim--u The combination, in the construction of a table for invalids, as set forth, of the revolving table bed or leaf with the column made adjustable and capable of being fastened in position, substantially as described, the Whole constituting a new and useful article of manu facture.
